DR-11800
16-BIT DIGITAL-TO-RESOLVER CONVERTER
DESCRIPTION
The DR-11800 is a small size, high
accuracy, 16-bit digital-to-sine/cosine
converter. Available in accuracies up
to 1 arc minute, the DR-11800 is con-
tained in a 28-pin, one-square-inch
hermetically sealed package and
requires +15 Vdc and -15 Vdc power
supplies. The reference conditioner
allows for either 115 Vrms or 26 Vrms
reference input for a 6.8 Vrms sin/cos
output. Two registers for the input of
the 16-bit (CMOS/TTL) natural binary
angle data allow for compatibility with
an 8-bit or 16-bit data bus.
Internally, the DR-11800 has a multi-
plying digital-to-sin/cos converter
made of two function generators and
a quadrant select network. Quadrant
information is available from the two
most significant bits. The two function
generators use the remaining angular
data along with the buffered reference
voltage. Similar to a multiplying DAC
(digital-to-analog converter), the DR-
11800 uses high accuracy resistive
ladder networks and solid state
switching to control the attenuation of
the reference voltage. The output
buffer amplifiers allow for up to 2 mA
output drive.
FEATURES

1 Arc Minute Accuracy
0.03% Radius Accuracy
Microprocessor Compatible -
8- and 16-Bit
APPLICATIONS
High accuracy, high reliability, small
size, low power consumption and
MIL-PRF-38534 processing avail-
ability, make the DR-11800 suitable
for industrial and military ground or
avionics applications. Possible appli-
cations include digital remote posi-
tioning, resolver angle simulators,
flight trainer, flight instrumentation,
radar and navigational systems, and
PPI displays including moving target
indicators. Other applications are syn-
chro/resolver system development
and test, and wraparound test of syn-
chro/resolver-to-digital converters.
